Abstract

A multiple-layer laminated shingle and a method of making the shingle are provided, in which at least one adhesive of high temperature resistance is applied for securing the shingle layers together, to reduce reliance on a roofer having to fasten (via nails, staples. or the like) through a narrow headlap zone of a posterior shingle layer in order to secure the posterior shingle layer to a roof, such that a vertically wide portion of the headlap area of the anterior shingle layer is presented to the roofer as a nailing zone.
